President Obama and Russian President Vladimir Putin held dueling news conferences as the G20 Summit wrapped up in St. Peterburg, Russia, Friday.

President Obama again made the case for a military strike against Syria. Putin again said military action would be illegal.

So the world community is divided over what to do in response to the alleged use of chemical weapons by Syrian President Bashar al-Assad's regime.

Now, President Obama is headed home to a country and a Congress that is also divided on whether the United States should take military action in Syria.
